摘要： Disclosed is a method of polishing a magnetic head slider whereby a by-processed step can be easily reduced. An air bearing surface of the magnetic head slider is polished with setting a bar that includes the magnetic head slider where a thin film magnetic head element is formed to reciprocate in a radius direction of a polishing plate, as well as rotating the polishing plate having a polishing surface. Polishing steps include a first polishing step of performing a height polish while rotating the polishing plate at a first velocity, and a second polishing step of performing a finishing polish while rotating the polishing plate at a second velocity sufficiently lower than the first velocity. The second velocity at the second polishing step is set so that an average linear velocity in the direction of the rotation of the polishing plate is equal to or lower than 0.032 m/s (preferably equal to or lower than 0.008 m/s). Consequently, the by-processed step that is generated on the air bearing surface of the magnetic head slider is reduced.

摘要： A magnetic playback apparatus and method with which a PLL phase-locked to played-back data operates stably even when the magnetic tape on which the data is recorded is transported at a high speed of several hundred times the recording speed. During high-speed playback of a magnetic tape, the speed of the magnetic tape is detected and using this tape speed information the free-run frequency of a PLL 2 is corrected in correspondence with the azimuth angles of magnetic heads HO, HE. The rotational period of a drum servo 3 is also corrected using the tape speed information.

摘要： A luminance signal Y and two color difference signals (R-Y), (B-Y) are separated from a color video signal. A color difference time division multiplex (TDM) signal is produced from the two color difference signals by a time base compression and time base multiplexing. A burst signal is added on the luminance signal and the color difference TDM signal as a time base information. The color difference TDM signal is recorded on an inner area of a disc. The luminance signal which has a wide signal band is recorded on an outer area of a disc which has a good frequency response characteristic. By separate recording of the two kinds of signals, a high resolution is obtained.
